Over the past three decades, heat has caused more U.S. deaths than any other weather-related hazard, including blizzards, floods, hurricanes, and tornadoes. Researchers expect U.S. heat deaths to reach into the thousands or tens of thousands by the end of this century. What does that mean for Arizona, where there are already roughly 600 heat-related deaths each year?

Read about how climate change will affect Phoenix and other Arizona cities.

Attempts to undermine voting rights and the corrosive influence of corporate money in elections are on the rise, putting our democracy—the foundation of so much of our environmental progress—at risk.

Last month, the Trump administration released a dire federal climate report late in the afternoon on the busiest shopping day of the year while they thought nobody was paying attention. (They were wrong.) Now they’ve revealed detailed plans for opening the Arctic National Wildlife Refuge to Big Oil, despite protest from Native tribes who hold the refuge sacred.

"The high point of my work week at Sierra comes on Thursday mornings," says senior editor Paul Rauber. That’s the day New York City–based illustrator Peter Arkle submits his ideas for "In Case You Missed It," a weekly roundup of environmentally themed illustrations. Rauber says Arkle’s sense of the absurd is "a perfect match to the head-spinning strangeness of environmental news in the modern era."

Even those of us who salivate at the sight of a charred, sizzling ribeye fresh off the grill have to admit that consuming animal products is just plain lousy for the environment. According to a recent report by the United Nations Intergovernmental Panel on Climate Change, animal agriculture harms the climate more than the combined emissions from every plane, train, car, bus, and boat in the world. Luckily, it’s getting easier to find tasty, satisfying alternatives to meat and dairy products that are good for the planet, good for your health, and easy on your wallet.

Here are 8 easy ways to begin cutting down on animal edibles and reduce your carbon footprint at the table.

Acting EPA administrator Andrew Wheeler has proposed that his agency ignore the public health benefits provided by the Clean Air Act’s mercury and air toxics standards. This arbitrary decree turns a deliberately blind eye to the dangers of particulate pollution, putting the health of tens of thousands of people in jeopardy and bailing out the coal industry, even as virtually all economic indicators suggest that coal can’t compete with cleaner, cheaper energy from solar and wind.
